Batch changing file extensions
We are moving from an OpenVMS server to a Unix server and I have a problem with ftp'ing files.
When I ftp the VMS server from the Unix server, I need to "mget" some files, for example "mget test_file*.txt;". The semicolon is necessary because OpenVMS has multiple versions of the file (eg test_file.txt;1, test_file.txt;2, etc).
When I do this i end up with the file "test_file.txt;2". I then need to convert this to remove the semicolon.
I have tried various methods and have found one that works :
for file in *.txt*; do
noext="${file%.*}"
mv "$file" "${noext#*.}.txt"
done
However, I have problems with this :
1. it renames ALL .txt files even if they have no ";" and version number.
2. it will only do one file extension at a time.
3. it is inefficient
What I want is to say "for all files with a semicolon in the file extension, rename the file to everything to the left of the semicolon".
Better yet, "give me all files matching *.txt; from theVMS server, and create them on the Unix server without the ;"
Any suggestions would be appreciated.

simpleftp
SIMPLEFTP(1) General Commands Manual SIMPLEFTP(1)
NAME
simpleftp - rudimentary ftp client
SYNOPSIS
simpleftp ftp://... [ ... ]
DESCRIPTION
simpleftp is a perl script that provides basic support for fetching files with FTP in a batch oriented fashion. It takes one or more ftp
URLS on the command line. The file(s) will be retrieved from the remote server and placed in the current directory with the same basename
as on the remote; i.e., ftp://ftp.isc.org/pub/usenet/CONFIG/active.gz is stored as active.gz in the current directory.
BUGS
simpleftp is an extremely poor substitute for more complete programs like the freely available wget or ncftp utilities. It was written
only to provide elementary support in INN for non-interactive fetching of the files in ftp://ftp.isc.org/pub/usenet/CONFIG/ without requir-
ing administrators to install yet another package. Its shortcomings as a general purpose program are too numerous to mention, but one that
stands out is that simpleftp does not understand the complete syntax of URLs, only the hostname and pathname parts -- it will not under-
stand username, password, port or parameter strings.
